Abstract

"Coke desulfurization procedure by pre-treating the coal with oxidizing reagents in solution", characterized by the contact of the coal, either during the purification process when dealing with raw coals, either in a silo or tank of adequate capacity and nature if These are purified coals, with aqueous solutions of oxidizing reagents, such as hydrogen peroxide, nitric acid, nitrates, hypodorites, permanganates or other oxidizing ions and acids. The nature and concentration of the reagents alone, mixed with each other or with other reagents destined for other carbon treatments, depends on the content of pyritic sulfur, distribution of pyrite in the carbonaceous mass, size of the carbon grains and their rank. Said solutions are made, through an appropriate distribution network, to the general stream of laundry water or to the silo that contains the coal to be treated, maintaining the concentrations and duration of treatment appropriate to each case to achieve the purpose pursued.
